63 * should include this helper. It generates the texture domain GLSL, produces the part of the
64 * effect key that reflects the texture domain code, and performs the uniform uploads necessary
75 * Call this from GrGLEffect::emitCode() to sample the texture W.R.T. the domain and mode.
78 * @param inCoords name of vec2 variable containing the coords to be used with the domain.
91 * Call this from GrGLEffect::setData() to upload uniforms necessary for the texture domain.
